UNITED STATES PATENT OFFICE.

CHARLES J. PILLIOD, OF SWAN ION, OHIO, ASSIGNOR TO LEVIS N. PILLIOD ANDHOLLY S. BASSETT, OF SAME PLACE.

FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 422,623, dated March 4,1890.

Application filed April 9, 1888.

To aZZ whom it may concern:

Be it known that 1, CHARLES J. PILLIOD, a citizen of the United States,and residing at Swanton, in the county of Fulton and State of 5 Ohio,have invented certain new and useful Improvements in Feed-Regulators;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to [O which it appertains to make and use the same,

reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification.

My invention relates to an automatic feed mechanism for roller-mills,and is designed for use in mills where the same stock is being fed totwo sets of rolls.

Heretofore it has been usual to feed the stock to each set of rollers bymeans of a spout delivering the stock to a division-board" placedcentrally of the two hoppers. Y

It has been found that the uneven delivcry of stock to the spout causesan impulse to be given to the body of stock in the spout, whereby thereis frequently a greater amount fed to one hopper than to the other,causing one set of rolls to be choked while the other set is runningclear of stock.

My invention consists in a receptacle for stock, supplemental to theusual hopper and placed upon the same, and provided with anautomatically -adjustable feed-gate pivoted. within the receptacle, andadapted to. receive the stock from the common source and deliver thesame in even quantities to each set of rolls when coacting with avertically-reciprocating feed-board moving within the receptacle.

In the drawings, Figure 1 represents a vertical section of the hopper ofa mill with my regulator attached thereto, the divider-being shown invertical section. Fig. 2 is a vertical section of the regulator, showingthe'inte- 5 rior in side view. Fig. 3 is a side elevation of thesupplemental hopper, showing the arm and counter-weight.

vider, showing a modified form of reeiprocat ing mechanism.

A designates the supplemental receptacle for stock, placed upon hopper Bof the mill, and having communication therewith through 5 5 an opening0, formed in the top of the hopper. directly beneath receptacle A.

D is a horizontal rod journaled in the sides of receptacle A, and havinga right-angled arm E adj ustably secured thereon by means of a set-screwF. Arm E is notched along its upper side, and a weight H is suspendedtherefrom by means of a bail secured to the weight, whereby the weightmay be suspended at any desired distance from rod D, and held in placeby reason of the bail engaging with the notches upon the arm whereveradjusted. V

I designates a feed-gate connected to rod D by being secured to hangersK, adj ustably connected to the rod by set-screws K.

L is a vertically-reciproeating feed-board moving in guides or ways Mformed in the sides of receptacle A.

N is a rotating shaft journaled in bearings upon the receptacle, andhaving eccentrics O, to which are connected pitmen P, which are attachedeither directly to the feed-board, as shown in Fig. 1, or indirectly bymeans of a bell-crank lever P, as shown in Fig. 5. 8o

Feed-board L is formed with its inner side fluted or corrugated, asshown atL',for a purpose hereinafter stated.

R represents the feed-spout inserted within the top of receptacle A andadapted to con- I,

vey the stock to the feed-gate to be divided and fed to the rolls.

S is a dividing-board placed within the hopper in parallel relation withthe rolls and at right angles to the feed-gate, and is designed toseparate the stock delivered to the hopper and by its inclination todirect the stock to the feeder within the mill.

In operation stock is fed through spout R and falls upon feed-gate L,which is adjusted to receive and sustain enough stock to insure itsfilling the. throat between the gate and board and thereby spread theentire length of the gate and to lie against the feed-board along itsentire length. The board when re- :00

ciprocated agitates the stock and causes it to feed evenly along theentire length of the board, thereby insuring an even feed to the dividerS. \Vhen, however, an unusual amount is received, the feed-gate isdepressed, raising weight II and opening the throat between the gate andfeed-board and allowing the surplus stock to pass without clogging.

The gate will be returned to its normal posi-' tion as soon as thesurplus stock is disposed of by the action of weight II. Feed-board L 1sreciprocated by the revolution of shaft N, which may receive motion fromany preferred source through the medium of the eccentrics and apitman-conneetion, either direct, as shown in Fig. 1, or by bell-cranklever, as shown in Fig. 5, or in any suitable manner. The reciprocationof the fluted feed-board agitates thestock which is collected in asufficient quantity upon the feed-gate to lie in contact with thefeed-board along its entire width, thereby feeding evenly to the hopperscommunicating with the divider S and insuring an equal amount to each,the quantity fed being determined by the opening between the feed-gateand feed-board, which may be regulated by the weight upon arm E.

It will be understood that I may substitute a spring for the arm andweight to control the operation of the feed-gate, and that thefeed-board may be rcciprocated through the medium of cranks upon shaft Nin place of eccentrics.

The machine is inexpensive in construction, readily adjusted, andadaptable to all forms of roller-mills.

lIaving described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a feed-regulator for roller-mills, the combination, with a hopper,of a supplemental hopper arranged above and communicating with the sameand a divider arranged between the two, an automaticvertically-adjustable feed-gate journaled within the supplemental hopperand at an angle to the divider, an arm attached to the feed-gate, and anadjustable weight sliding upon the arm to vary the posit-ion of thefeed-gate, and a vertically-reciprocating feed-board, located alsowithin the hopper adjacent to and parallel with the free end of thefeed-gate and moving past the same to feed the stock into the machine,substantially as shown and described.

2. In a feed-regulator for roller-mills, the combination, with the frameof a roller-mill, of a hopper, a shaft journaled within the hopper, anda feed-gate secured to said shaft, the feed-gate being verticallyadjustable to vary the internal area of the hopper, an arm attached tothe shaft without the hopper, and an adjustable weight sliding upon thesame to vary the position of the feed-gate, and avertically-reciprocating feed-board located within the hopper adjacentto and parallel with the free end of the feed-gate and reciprocatingpast the same substantially as shown and described.

3. In a feed-regulator for roller-mills, the combination, with a hopperA, of a shaft 1), journaled within the same, a feed-gate I, attached tothe shaft, said shaft having an arm E, carrying an adjustable weight ll,bymeans of which the vertical position of the free end of the feed-gateis varied, and a verticallyreciprocating feed-board L, corrugateddescribed, located within the hopper and working past the free end ofthe feed-gate to feed the stock to the rolls, all arranged and adaptedto operate substantially as shown and described.

In testimony that I claim the foregoing as my own I hereby afiix mysignature in presence of two witnesses.

CHARLES J. PILLIOD.
